ROM Control (Page mode)
mode is set by the page ROM control register.
(1) Operation and how to set the registers
(2) Signal pulse
Note: Set the number of waits (“n”) using the control register (BnCSL) in each block address
This section describes ROM page mode accessing and how to set registers. ROM page
mode is specified only in block address area 2.
<OPGE> of the PMEMCR register to “1” sets the memory access of the block address
area to ROM page mode access.
The TMP92CM22 supports ROM access of the page mode. ROM access of the page
ROM page mode is set by the page ROM control register (PMEMCR). Setting
The number of read cycles is set by the <OPWR1:0> bit of the PMEMCR register.
area.
The page size (The number of bytes) of ROM in the CPU side is set by the
<PR1:0> of the PMEMCR register. When data is read out up to the border of the
set page, the controller completes the page reading operation. The start data of
the next page is read in the normal cycle. The following data is set to page read
again.
